Problem:
 app(app(rec(),h),app(g,0())) -> g
 app(app(rec(),h),app(g,app(s(),x))) -> app(app(h,x),app(app(rec(),h),app(g,x)))

Proof:
 DP Processor:
  DPs:
   app#(app(rec(),h),app(g,app(s(),x))) -> app#(g,x)
   app#(app(rec(),h),app(g,app(s(),x))) -> app#(app(rec(),h),app(g,x))
   app#(app(rec(),h),app(g,app(s(),x))) -> app#(h,x)
   app#(app(rec(),h),app(g,app(s(),x))) -> app#(app(h,x),app(app(rec(),h),app(g,x)))
  TRS:
   app(app(rec(),h),app(g,0())) -> g
   app(app(rec(),h),app(g,app(s(),x))) -> app(app(h,x),app(app(rec(),h),app(g,x)))
